HARRY B. MILLER United States Patent Winding Company, Cranston, R.I., acorporation of Massachusetts Application March 4, 1958, Serial No.719,095

2 Claims. (Cl. 57-130) The present invention relates to a textilespindle and more particularly relates to a textile spindle adapted tomount a conical package core thereon.

In the following specification and claims the term yarn is employed in ageneral sense to apply to all kinds of strand material, either textileor otherwise, and the designation package is intended to mean theproduct of a winding or twisting machine whatever its form.

In many textile operations it is desirable to have yarn wound on conicalpackage cores. However, most prior art spindles for twisting machinesare not adapted to mount cones so it is customary to wind a ring twisterpackage on a pirn or bobbin. Sometimes such packages are unsuitable fora subsequent operation or for shipping purposes and the yarn must berewound from the pirn or bobbin onto a cone necessitating an extraoperation.

One object of the present invention is to provide a textile spindlewhich will adapt a twisting machine to utilize conical package cores.

Another object of the present invention is to provide a textile spindlemeans for quickly and easily mounting a conical package core thereon.

Another object of the present invention is to provide a textile spindlehaving means for mounting and rotating a conical package core.

Another object of the present invention is to provide a textile spindlehaving means for mounting a conical package core thereon wherein saidcore can be quickly and easily removed therefrom.

Another object of the present invention is to provide a textile spindlehaving means for mounting a conical package core thereon which isinexpensive to manufacture, and which is durable and economical in use.

Other objects of the invention will in part be obvious and will in partappear hereinafter.

The invention accordingly comprises the apparatus possessing theconstruction, combination of elements and arrangement of parts which areexemplified in the following detailed disclosure, and the scope of theapplication of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention,reference should be had to the following detailed description taken inconnection with the accompanying drawings wherein:

'Fig. l is a sectional front elevation of the textile spindle of thepresent invention with a conical package core mounted thereon; and

Fig. 2 is a front elevation with parts broken away of the textilespindle of Fig. l but showing a package wound on the core and said corein the doif position.

The textile spindle of the present invention is suitable for use with aring twister and is so constructed that a conical package core can bequickly and easily placed thereon and securely held. The core can thenbe rotated with substantially no slippage, and yarn wound thereon. Afterwinding, the package comprising said 2 core and the yarn thereon can bequickly and easily removed from the spindle.

Referring now to the drawing wherein a preferred embodiment of thetextile spindle of the present invention is disclosed, the spindlecomprises a substantially rigid blade 10 having a substantiallycylindrical upper por tion 11, a tapered lower portion 13 adapted to bejournaled in a spindle swing, and a short tapered section 20. Section 20fits securely in the axial hole through whorl 12 to mount said whorl onsaid blade. Said whorl is provided with a pair of radially disposedupstanding driving vanes 22. Such a spindle is well known to thoseskilled in the art.

Cone base holder 14 is slidably mounted concentric with the axis ofblade 10 and about the upper portion 11 thereof. Holder 14 has afrusto-conical surface 26 tapered to fit inside of core C, a chamferredupper surface 24 and a diametrol slot 28 in its lower surface, said slotcapable of engaging vanes 22. Abutment 16 is secured to the upperportion 11 of the blade at a suitable location by set screw 30. A cap18, having a cylindrical body having a diameter substantially equal to Iopening 19 in the nose of core C, rounded and closed on one end and openon the opposite end to receive blade 10 is secured to said blade bymeans of a press fit.

The textile spindle of the present invention operates in the followingmanner. Holder 14 is aligned so that groove 28 engages vanes 22 as inFig. 1. A core C is set over the spindle and pushed down so that cap 18protrudes through opening 19. Chamferred surface 24 guides the base ofcore C into alignment with conical surface 26. Core C is pressed ontothe spindle so that it is held firmly by surface 26 engaging the insideof said core and is held in axial alignment with blade 10 by surface 26and cap 18.

The spindle is rotated by means well known to persons skilled in theart, for example, a driving belt in contact with whorl 12. Vanes 22engaging groove 28 rotate holder 14 with the spindle.

To doff a wound package of yarn the package is lifted upwardly in theaxial direction of the spindle. Opening 19 slides over cap 18 as thepackage is pulled. Holder 14, being in firm engagement with core C,moves axially therewith until said holder strikes abutment 16 as shownin Fig. 2. The sudden contact between holder 14 and abutment 16 stopssaid holder from continuing its axial movement and jolts core C loosetherefrom, disengaging the package from the spindle.

Whereas the present invention is herein disclosed in an embodimentparticularly suited for use on a ring twisting machine it should beunderstood that it can be used on any twisting machine, e.g. anuptwister or captwister, and since certain changes may be made in theabove apparatus without departing from the scope of the invention hereininvolved, it is intended that all matter contained in the abovedescription or shown in the accompanying drawing shall be interpreted asillustrative and not in a limiting sense.

What is claimed is:

1. A textile spindle adapted to hold a conical package core, saidspindle comprising a blade having a substantially cylindrical upperportion, a whorl on said blade, a member slidably mounted on said bladeand adapted to engage the inside of said core, cooperating means on saidwhorl and member for rotating said member, a cap fixed to the upper endof said blade and adapted to be engaged by the nose of said core, and anabutment fixed to said blade between said member and said cap.

2. A textile spindle adapted to hold a conical package core, saidspindle comprising a blade having a substantially cylindrical upperportion, a whorl on said blade, 3,
